Exterior Painting in the GTA

Late May through mid-September is the reliable window. April and October are workable but risky, the constraint is the overnight low, not the afternoon high. Acrylic exterior paint needs sustained temperatures above about 10 °C to coalesce into a continuous film, and a warm day followed by a 4 °C night can leave you with a coating that never properly forms. Book in winter for a spring slot; the good crews fill up by March.

Seven to ten years on wood siding with sound prep, ten to fifteen on properly prepared brick or stucco. South and west elevations always go first because they take the UV and thermal load, it is normal to touch those two faces up once during the life of the overall job. Anything failing inside three years is a prep failure, not a product failure.

Yes, and it is permanent, that is the part people are not always told. Painted brick cannot be reasonably returned to bare brick; stripping is expensive, rarely complete, and can damage the face of the masonry. It also changes how the wall breathes, so it has to be done with a vapour-permeable masonry coating rather than standard exterior acrylic. We will walk you through the trade-off honestly before you commit, because the decision is effectively irreversible.

Yes. Chalked aluminium is one of the better repaint candidates in the GTA because the substrate itself does not rot. It needs a thorough wash to remove the oxidised chalk layer, a bonding primer, and an acrylic topcoat. Done correctly it looks like new siding for a fraction of replacement cost.

We stop and cover. Rain inside the recoat window is the single most common cause of surfactant leaching, those brown streaks you see on freshly painted houses. We would rather stretch a job by two days than hand you a wall that streaks the first time the weather turns.
